I will let you know soon- what will fit in the trunk, what won't ...
I'm dealing with idea of Full Size Spare Wheel, that I need to find place for...
But as always, if I can complicate something for sure I will do...

Call me sick, lame, lazy, penny sever - I'm trying to use my 2015 Corolla brand new full size wheel as a full size spare wheel for Crosstrek. Both are: 17" size, both have 5x100 mm Wheel Bolt Pattern, Corolla wheel need Crosstrek size tire, either cheap one or one of my own used ones... and ideally should fit in Crosstrek compartment !!!

Sounds pretty straight forward, isn't it ???




Sold Corolla with "donut" and full size spare is hanging around... instead of spending money on spare wheel, using what I have makes more sense. Different wheel pattern and design ? I do NOT care, it is a SPARE, that's it.

The same wheel did fit in Corolla trunk space and I hope, I will accommodate it in Crosstrek also...



I'm gonna play with it today, let you know what happened...

 

This is the spare tire compartment in the Wilderness with the OEM donut spare,

And this infuriates me.

So you get this all-road Wilderness, big clearance, all rough and ready, do the trails, get your rock on, and ka-bam a sidewall gets sliced. There you are above tree line at 12,000 feet and all you have is this crappy T-spare in that back to get you back down the mountain. One of the things I did like about my 2004 Forester is that is had a real spare in the back, which I had occasion to use. My 2003 Impreza TS wagon came originally with that stupid donut, but the wheel well was just big enough to put a full size steeley with tire in there, which I did. Which amusingly enough the guy who stole my Impreza used when he buggered up one the rear rear customs I had put on.

Whenever I am out on road trips, and generally am far away from tire shops or at times, civilized lands, I always have that fear lurking in the back of my head that I'll get a blow out and be forced to use that stupid donut and pray that it will survive long enough.

Yeah, we can get into why the auto makers did this. But we all know why.

Hm, pretty tight fit...

 

That was my estimation, also. A well used, deflated tire should fit.

 

It defeat the purpose to have a spare tire, doesn't it? will you carry a pump then?

 

Look please, I copy this post from different thread:

I got a flat on the freeway today and tried to put the stock 0 PSI tire in the well. It did not fit. I couldn't force it. View attachment 300440 View attachment 300441

Damm...

 

That is not a Yokohama Geolander A/T G015 so I am guessing it is an 18 inch diameter tire??
I don't think the Subaru is a Wilderness.
The tire needs to be turned up side down so the hold-down bolt fits.
My 2024 Wilderness may be different.

 

Just a reminder: Regardless of whether you use a spare tire or another tire, the rolling circumference may not deviate from the rolling circumference of the other tires by more than +/- 2%. Otherwise, there is a risk of damage to the drive system. This percentage was already specified by Subaru Germany years ago.

 

Problem is the spare Subaru gives you does not meet that spec.

 

There’s only a tenth of an inch difference in tire diameter between a Wilderness and non-wilderness.

 

I meant the just now flat tire would fit, the donut spare would be inflated and installed (temporarily).
I do carry a 12VDC tire pump and battery impact wrench so I can remove the lug nuts.
The tenth of an inch may be the 'show stopper'.

 

got it , I misunderstood

 

Hey guys!

I've got two information. First - and this is very important for ALL Crosstrek users:

Subaru Crosstrek Wheel Compatibility Chart

Subaru Crosstrek Wheels Interchange

Subaru Crosstrek

bolt-patterns.com

It is a place, where you can check any combinations off wheels that will fit your Crosstrek or not !!!

And second information - answering question:
If 2015 Corolla S wheel will fit 2021 Crosstrek Premium ???

Subaru Crosstrek Wheel Specs Comparison

Interchangeability​
Bolt pattern​	5x100	5x100
Yes, these parameters match.
Center bore​	56.1 mm	54.1 mm
No, these parameters are different. You can install Hub Centric Rings to change your center bore size. Please keep in mind that this only works if the center bore of the rim is larger than the center bore of the car. You cannot reduce the center bore of your vehicle in any way.
Thread size​	M12 x 1.25	M12 x 1.5
No, these parameters are different. Use properly threaded bolts to keep the wheels securely in place.
You can’t directly install wheels from 2015 Toyota Corolla on 2021 Subaru Crosstrek. You may need to perform some modifications.

That's all I need to know. Case closed. If I want to get rid of "donut" wheel - either/or have to get original Crosstrek wheel and tire and than having problem with placing this in/out of the car or go with smaller AT wheel from thread below:

Thank you ALL for sharing your thoughts...

 

Guess we should have bought the Outback.
They get a full size spare: The 2025 Subaru Outback.
Putting my spare in the back seat saved me how much???

 

Well, I took a different route:
- just ordered from eBay used in good condition original OEM wheel - matching rims on my Crosstrek...



Just before winter will install new set of tires /stock size/ and the best one from my car will be installed on this extra rim. No TPMS - just "fifth" SPARE only wheel with the same size tire. Temporally wheel be placed behind passenger seat until will come up with better idea...

Will attached some photos later...

 

I would do without the spare tires altogether. When was the last time you changed a flat tire ? 10 years ago at least for me. I am currently working on a "Support" to hold up the cargo area floor cover when there is no spare tire underneath the floor cover. I will also get a tire plug kit and some way to inflate a flat tire.
In this way I'll save the weight of a spare tire and all of the tools needed to replace it and I'll gain some much needed cargo area.

 

I'm with you in regards to flat tire changes. I think I've done one in my years of driving our personal vehicles. I've helped others though many times
I carry a mini compressor and the cheap tire patch repair kit, as this has been used many times by me with excellent results. The spare would be good for a side wall or rim issue IMO. Again, better to have it and not need it, than to not have it and need it I guess. I have yet to prepare a flat tire kit (compressor/tire repair kit) for the new CT, but will be getting one prepared soon. Hopefully before winter

 

That is actually a good plan for highway driving. Changing a flat tire on the side of the road is very dangerous and there is a good possibility you would not be able to loosen the lug nuts with the OEM wrench. Back in the ole days when I could change a flat tire it was usually raining or snowing or dark. Just call roadside assistance and have them tow you to wherever. Right now I have Subaru and AAA roadside assistance. In some parts of the US of A you need a satellite phone or 2 Meter rig to call for help.

Driving off road is totally different. Roadside assistance will not go off road, that is why it is called "roadside". I have made arrangements with a local towing company to do off road recovery on my Tree Farm. The small donut spare will not give me enough ground clearance or the traction I need to get back to a public highway. Even though I have a full size spare and the tools to actually change a flat out in the woods I am probably not capable of actually doing it. Don't know how much my full size spare on a steel rim weighs, but it is really heavy. But at least my off road recovery company could change the flat, but only if I can provide a full size spare.

If I go to off road Parks I do so with other 4WD vehicles that have recovery hooks and real recovery points. I need real recovery points to go off road with my off road Club, that is a Rule. Same thing if I go to an off road Park where you pay to play. The Wilderness does not have real recovery points. My off road recovery company says he would put a strap around a wheel to recover me. That is the strongest part of the vehicle. He would not use a J hook on an A-arm, I asked.

The above is what I have learned so far. Hopefull this is usefull information for other Wilderness owners.

 

I suppose if you’re just using your car for urban commuting, running without a spare is a possibility … but personally, I’d prefer to change my own tire rather than sit in a disabled vehicle for a couple hours waiting for AAA to show up. If you do longer road trips, though, I strongly feel that traveling without a spare is pretty foolish.

IIRC, I think I’ve had four flats on my Crosstreks in the last few years. Changing a tire is not rocket science, and I think it’s something that every driver should absolutely be able to do.

 

I don't know how foolish it is to go without a spare, I haven't had a flat tire in years and even as you say, once a year or so ? Many new cars don't even have a spare tire due to how much they weigh. The only reason I carry my OEM spare tire now is because it holds up the cargo area floor. I think I can support the floor in another way and do without the spare completely while carrying a tire repair kit and some way to ad air to the tires. I just need to get on that !! I also have AAA so I think I can do away with the spare. My Corvette does not have a spare tire.
I'd really like to see airless tires.

If I were to go off roading then Yes, I would carry the OEM spare.

 

Maybe that is why the flat tire is stored in the spare tire area, to hold up the cargo area floor. Refer to Post #1 above: Owner's Manual page 431 paragraph "16." states "Store the flat tire in the spare tire compartment. .....".
So my question still remains: Will the full size flat tire actually fit in the spare tire well???? Has anybody actually done it?
Since the flat tire is wider than the spare (I think), does that lift the cargo area floor up higher?

Fixed it for ya.

A full-size flat tire will not fit into the spare tire well, despite being fully deflated. Folks here who have tried carrying a full-size spare OVER the spare tire well claim it raises the cargo floor panel up to the level of the lift gate bottom sill.

 

The stock tire didn't fit in my spare tire well, even with a huge sidewall gash, so it was completely deflated. The diameter of the tire was bigger than the sheet metal of the spare tire well.

I got like three unrepairable flats in the stock tires in my first year driving in the city. I found the factory scissor jack and wrench worked fine. I wouldn't drive without a spare.

 

Everybody is different. My goal is simple: to be self-sufficient.... will carry not one- but 2 spare wheels. "Donut" in factory place and fifth full size spare wheel without TPMS.
Here we go, rim is already waiting for a tire...




Used rim in very good condition from eBay- $120.00 Peace of mind- Priceless !
